Yes, with your patch and mine I can capture the same way as with the
5.4 kernel :-)
The pink color issue is still present but it is orthogonal to this problem.
Could you please submit your patch formally to the list? Please
include my attached patch as 1/2 and yours as 2/2.
Also, please add the following tag to your patch:

Subject: [PATCH 1/2] media: imx7: csi: Fix regression for parallel cameras on i.MX6UL
Commit 86e02d07871c ("media: imx5/6/7: csi: Mark a bound video mux as
a CSI mux") made an incorrect assumption that for imx7-media-csi,
the bound subdev must always be a CSI mux. On i.MX6UL/i.MX6ULL there
is no CSI mux at all, so do not return an error when the entity is not a
video mux and assign the IMX_MEDIA_GRP_ID_CSI_MUX group id only when
appropriate.
This is the same approach as done in imx-media-csi.c and it fixes the
csi probe regression on i.MX6UL.
Tested on a imx6ull-evk board.
Fixes: 86e02d07871c ("media: imx5/6/7: csi: Mark a bound video mux as a CSI mux")
